Im at my witts end trying to figure this out. My 6 year old son has PANDAS and is on continuous antibiotics. I have a 3 year old son who a few months ago had a few weeks of unexplaned middle of the night only vomiting followed by loose stools during the day. During this time my PANDAS child was in a major flare mode. Finally took my youngest to the drs when we noticed his throat was swollen and the fast strep test came out barely positive and we had out whole family treated with antibiotics. Both kids got better. A few weeks later same thing happened..my youngest had unexplanable night vomiting for days with loose stools during the day. Took him back to the ped, they found nothing, strep came back fine. No other symptoms once again and was acting completely fine the rest of the time. But again, my PANDAS child was off the wall once again..we explained to the ped about PANDAS and my other son so due to this he placed my youngest on antibiotics anyway just incase. Sure enough..both kids got better. Now for the third time..my PANDAS child is off the wall once again and my youngest started the loose stools 3 days ago and the vomiting last night. Took him to the ped again, this time irritated, and they cant find anything wrong.. throat looks fine, no symptoms not even a runny nose. He is developing fine, no abnormal behavior to make me think PANDAS, no skin rashes or any other issues to think food intolerance (though he is on restricted diet with my other child, no dairy, beef peanut, egg, etc). The ped mentioned maybe my other son is kickign something out with the antibiotics which is making my youngest sick. But if he is so typical then why isnt it showing up? Does anyone have any problems with sibling illnesses?
Other then chronic ear infections as a baby/toddler, we have had no developmental issues/behavior issues/tics/ocd or anything abnormal with my youngest.
Thanks
